Abstract
A shaving head is provided that includes one or more cutting blades and actively driveable skin stretching device arranged behind said cutting blade. The actively driveable skin stretching device operates to reduce the possibility of causing nicks and cuts or skin irritation during a shaving operation. The shaving head provides a pivot axis between the shaving head and a handle that is either attached or attachable to the shaving head. The pivot axis is arranged to be essentially parallel to the cutting blade. By providing the pivot axis, the force ratio between a force applied to the actively driveable skin stretching device and forces applied to other parts of the shaving head may be kept constant for different angles of the handle. This improves the functioning of the actively driveable skin stretching device.
